What does the LOW-COOLANT indicator light mean in a Buick car?
1 Answers
LOW-COOLANT is an indicator light in Buick cars that illuminates when the engine coolant level is too low. Here are the details: 1. Normal conditions: Under normal circumstances, the coolant circulates through the engine water jacket, cooling system, and air conditioning heating system without significant reduction. If the LOW-COOLANT light comes on, it is highly likely that there is a leak in the cooling system pipes. 2. Special conditions: For older Buick cars, coolant leaks in the cooling system often occur at the connection points between rubber hoses and metal pipes. The main causes of leaks are aging rubber hoses and insufficient tightening force of the clamps. When replacing, it is best to replace both the rubber hoses and the clamps together.
